Timecard GuruHow this conversion works
Keep the 1 whole hour. Convert the minutes on their own: 30 ÷ 60 = 0.50. Add that fraction to the hours: 1 + 0.50 = 1.50.
Write 1.50 on the timesheet. Do not write 1.30. Putting the minutes after the dot is the usual mix-up, and it short-changes the time. 30 minutes is 0.50 of an hour, so 1 hour 30 minutes is 1.50, not 1.30.
